Kutentha ndi nyengo zovuta zimafuna zitsulo zolimba
Ntchito ya Mars Science Laboratory (MSL), yomwe idakwanira kufika kwa chidwi cha Rover pa Red Planet pa Aug. 6, 2012, idakhala chifukwa cha zaka zambiri za kafukufuku wamakono ndi nzeru zaumunthu pankhani ya sayansi. Chombocho chinatenga pafupifupi chaka kuti chiyende kuchokera ku Dziko kupita ku Mars ndipo poyamba chinkafunika kugwira ntchito kwa zaka ziwiri zokha (ntchito yake yakhala yayitali kwa nthawi yayitali).
Kodi Cholinga Chofuna Kudziwa N'chiyani?
Malingana ndi NASA, "Chidwi ndi galimoto yaikulu, robot yamphamvu sikisi yopita ku Gale Crater pa Mars.
Ntchito yake: kuwona ngati Mars akanakhala atathandizira miyoyo yaing'onoting'ono yotchedwa microbes ... ndipo ngati anthu akanatha kupulumuka kumeneko tsiku lina! Kuwonjezera pa zintchito zaumunthu zomwe zimatithandiza kumvetsetsa Mars ngati malo a moyo, Zosakondweretsa zigawo zofanana ndi zomwe munthu angafune kufufuza Mars (thupi, ubongo, maso, mkono, miyendo, etc.). Zikuoneka kuti mbali zina za Mars Science Laboratory rover zimakhala zofanana ndi zomwe zamoyo zilizonse zimafunikira kuti zikhale "zamoyo" komanso zokhoza kufufuza. "Mbali zimenezi zimaphatikizapo zojambulajambula, makompyuta, kayendetsedwe ka kutentha, masensa ndi makamera, manja a robot, mphamvu yamagetsi, ndi mauthenga a mauthenga.
Zida ku Mars Rover Kukhumba
Pofuna kukambirana momveka bwino za kayendetsedwe ka malo ozungulira, kulowa mmlengalenga, kukwera pansi, ndi kufufuza, zomwe zimaphatikizapo kutentha kwa 3,790 ° F (2,090 ° C) mpaka -131.8 ° F (-91 ° C), chidwi ndi magalimoto ake amamanga pogwiritsa ntchito zitsulo zopangidwa ndi zitsulo.
Pano pali chithunzi cha zitsulo zina zomwe zimagwiritsidwa ntchito pomanga chidwi ndi galimoto yonyamula katundu:
Metal | Gwiritsani ntchito |
| Titanium tubing | Miyendo Yokonda chidwi |
| Mitengo ya Titanium | Onjezerani kukwera mkati mwa magudumu a chidwi |
| Taniketi ya titaniyamu | Chimodzi mwa mawonekedwe a parachute omwe amagwiritsidwa ntchito potsatira kayendedwe ka rover |
| Aluminium | Maganizo a magudumu |
| Aluminium mortar | Chimodzi mwa kayendedwe ka parachute. Gwiritsani chingwe kuchokera ku aluminium billet |
| Aluminium uchi | Anapanga maziko a Atlas V, chotengera chodzidzimutsa |
| Bronze | Zolemba za DU® zitsulo zopangidwa ndizitsulo ndizofunikira kwambiri muzitsulo za rover. |
| Mkuwa | Chikhumbo chimasonkhanitsa zitsanzo m'maselo, omwe amasindikizidwa mu uvuni wa pyrolysis mwa kuyika sela ya mkuwa kukhala mpeni wa mpeni ndi mphamvu ya mapaundi 250. Chitsanzocho chimatenthedwa mpaka 1100 ° C kuti awononge. |
| Yotsogolera | Chidwi chimakhala ndi gawo la Radioisotope Thermoelectric Generator limene lingagwiritse ntchito PbTe / TAGS thermocouples yotulutsidwa ndi Teledyne Energy Systems. |
| Tellurium | |
| Germanium | |
| Antimoni | |
| Siliva | |
| Chitsulo chosapanga dzimbiri | Jenereta zachitsulo zosapanga zitsulo zinapangitsa kuti gasi yowonjezereka ikugwiritsidwa ntchito poyambitsa parachute ya chidwi kuchokera ku ndegeyo. |
| Rhenium | Bungwe la RD AMROSS RD-180 linayambitsa njira yoyendetsera Atlas V. Rhenium yomwe imagwiritsidwa ntchito mu jet turbine. |
| Tantalum | 630 tantalum multianode capacitors ali ndi mphamvu zowonjezera gawo la ChemCam laser kutsogolo Chidwi |
| Tungsten | Chipolopolo cham'mbuyo cha galimoto yolowera mumlengalenga chinatulutsa zigawo ziwiri zazitsulo zooneka ngati tungsten kuti zitha kusintha malo ozungulira ndegeyo pamene ikuyandikira Mars. Ma ballast omwewo anali olemera makilogalamu 75 kapena 25 kilogalamu. |
| Gallium | Maselo a photovoltaic odzaza ndi zitsulo zazing'ono ndi zazing'ono zimapatsa chidwi Chidwi ndi mphamvu masana. |
| Indium | |
| Germanium | |
| Silicon | Mafuta a silicon omwe ali ndi mayina oposa 1,24 miliyoni ali m'gulu la chidwi. |
| Mkuwa | Ndalama yojambula mu 1909 (pamene inali yambiri yamkuwa) ili pamtunda kuthandiza asayansi kuti asinthe makamera pakalipano akutumiza zithunzi ku Dziko lapansi. |
